The Subtitles Panel was added in Shotcut 24.08
The Subtitles Panel can be used to add subtitles to a project. Subtitles can only be added to the Timeline. They can not be added to the playlist or clips. We recommend to save subtitle editing until the timeline editing is complete because moving or cutting clips on the timeline will break the subtitle synchronization.
Subtitle Tracks
To start editing subtitles, click the “add” button and give the subtitle track and name and language.
After the subtitle track is created the subtitle track area will appear in the timeline above the top video track. Multiple subtitle tracks can be added. But only the currently selected subtitle track is shown in the Subtitle Panel and the Timeline.
Adding Subtitles
Click the “Add subtitle” button to make a new subtitle item at the cursor position. Then type in the “Current” text area to add the text.
Importing Subtitles
Subtitles can also be imported. Supported subtitle import formats include: SRT, VTT, ASS, and SSA. Subtitles are imported at the current cursor position.So be sure to place the cursor before importing subtitles from a file.
Exporting Subtitles
Subtitles can be exported to a file. Subtitles are exported in SRT format.
Embedding Subtitles
When exporting a Shotcut project, subtitles will be embedded in the output file if the file format supports it. Formats that commonly support subtitles include MKV, MOV and MP4.
